The MEJB is configured to permit only users in the asadmin group to execute its methods. You must login as a user in the asadmin group before trying to use the MEJB. See: http://docs.sun.com/source/819-0079/dgsecure.html#wp22278
here is an code example:
// Authentication
ProgrammaticLogin pl = new ProgrammaticLogin();
Boolean success = pl.login("j2ee","j2ee");
// Use the MEJB
Management mejb = mhome.create();
